Let's evaluate f(-1)
Start with the given function
Plug in
Raise -1 to the 3rd power to get -1
Multiply -1 and -1 to get 1
Raise -1 to the 2nd power to get 1
Multiply 1 and 1 to get 1
Add 1 and 1 to get 2
Multiply 3 and -1 to get -3
Add 2 and -3 to get -1
Add -1 and 4 to get 3
--------------------------------------------------
Now let's evaluate f(0)
Start with the given function
Plug in
Raise 0 to the 3rd power to get 0
Multiply -1 and 0 to get 0
Raise 0 to the 2nd power to get 0
Multiply 1 and 0 to get 0
Add 0 and 0 to get 0
Multiply 3 and 0 to get 0
Add 0 and 0 to get 0
Add 0 and 4 to get 4
--------------------------------------------------
Now let's evaluate f(1)
Start with the given function
Plug in
Raise 1 to the 3rd power to get 1
Multiply -1 and 1 to get -1
Raise 1 to the 2nd power to get 1
Multiply 1 and 1 to get 1
Add -1 and 1 to get 0
Multiply 3 and 1 to get 3
Add 0 and 3 to get 3
Add 3 and 4 to get 7
